Hello,

I'm using pe:ckEditor in a paginated form (i.e. not all form elements are on page at same time), pages loaded via ajax. Everything works fine if I don't use p:ajax tags or works fine the first time a page is loaded that includes the ckeditor. However, if I load another form page (that doesn't have a pe:ckEditor), I get the following error:

Code: Select all

Uncaught TypeError: Cannot read property 'document' of null
e.extend.getFrameDocument
j.add.init.C.on.C.addMode.getSnapshotData
j.add.init.n.on.o
a.event.on.m
a.event.fire
a.editor.fire
e.extend.getSnapshot
e.extend.checkDirty

PrimeFacesExt.widget.CKEditor.PrimeFaces.widget.BaseWidget.extend.checkDirtyFromTimerprimefaces-extensions.js.jsf:52

If I then return to the page, that had the ckeditor, I get this error:

Code: Select all

Uncaught TypeError: Cannot call method 'getFrameDocument' of null

And here is an excerpt of the page:

            </h:form>
        </p:outputPanel> 
    </ui:define>

    
    </ui:define>

    
Again, If I use the pe:ckeditor tag without the p:ajax tags, these errors don't present.

Thanks,

Hi,

i can check it for you but could you please provide a simple maven sample app + issue?
I don't have enough time to create samples etc.

Thanks.

Thanks for your reply,

I have been able to avoid the errors by destroying the ckeditor objects when changing form pages. This is perhaps not an optimal solution, but it seems to work as intended.

Code: Select all

<pe:ckEditor widgetVar="editor#{item.number}" width="75%" height="#{item.question.responseHeight}" value="#{item.response}" toolbar="[['Bold','Italic','Underline','Strike','Subscript','Superscript','Format','Font','FontSize','-','RemoveFormat','-','Cut','Copy','Paste','PasteText','PasteFromWord','-','NumberedList','BulletedList','-','Outdent','Indent','-','SpellChecker']]">                                
                                <p:ajax event="dirty" onstart="passTest.callCleaner();return false;" partialSubmit="true"  listener="#{testBean.handleResponse}"/>
                                <p:ajax event="change" onstart="passTest.callCleaner();return false;" partialSubmit="true" listener="#{testBean.handleResponse}"/>
                                <p:ajax event="initialize" onstart="passTest.registerEditor(editor#{item.number});return false;" partialSubmit="true" listener="#{testBean.handleResponse()}"/>
                            </pe:ckEditor>

Code: Select all

passTest.registerEditor = function(id){
    passTest.editors.push(id);
    passTest.editor=true;
}
And then when I load up (via ajax) another page, I call:

Code: Select all

passTest.removeEditors = function(){
    if(passTest.editor){
        for(var i=0, len=passTest.editors.length; i < len; i++){
            passTest.editors[i].destroy(true);       
        }
        passTest.editor=false;
        passTest.editors.length=0;
    }                
}

Hmm, the weird thing is that it works without p:ajax. Does it really work for 100% without p:ajax?

Yes, it seems to. I replicated issue in simple example: http://undermensch.googlecode.com/svn/trunk/.
I also created an issue: http://code.google.com/p/primefaces-ext ... ail?id=217
